Thanks to Kessil’s dense matrix LED arrays and specialized optics, you can cover your tank in brilliant light while blending spectrum better than any other LED light on the market. Using Kessil Logic, tuning the light for optimal coral growth and colouration is easy since the A500X will automatically adjust to a balanced spectrum for the light colour that you want to see.
